For some users who may not need voice access, a data-only smartphone plan may be the way to go. On November 6, with the launch of the Android 2.0 Motorola Droid flagship phone, the largest US carrier will be unveiling three plans–a $30 basic internet plan, a $45 plan that includes Exchange and browsing, and finally a $50 plan for all the data plus Exchange email support and no voice plan. The first two plans require the addition of a voice plan while the $50 plan can let a smartphone user fly solo without the baggage of a voice plan.

Update: According to Stephen Skarlatos on Twitter, the $45 plan is for business accounts. You can still use the $30 personal data plan with an Exchange account. Details for the clarification can be found at Gearlog.

For Windows Mobile owners of the Touch Pro2 and HTC Imagio, would you want a data-only smartphone plan for $50?

Perhaps for some business customers who may require two devices–one for voice and one for data–this may make sense as Verizon Wireless’ CDMA network (and Sprint’s as well) does not support simultaneous voice and data over 3G. This would allow an enterprise customer to be on one cell phone having a conference call and be on a Touch Pro2 sans voice access on the web to do some basic research while mobile.

It’s also rumored that tethering will come at a later point in time for the Droid.
